Passing Tag name as Gradle parameter to rollback commands does not work

[UlrichLohrmann]

I have the following activity configured:

schemaInit {
    searchPath "${projectDir}"
    changelogFile "db-changelog/changelog-master.xml"
    url "jdbc:postgresql://${System.env.PG_HOST}:${System.env.PG_PORT}/db_flw"
    username "..."
    password "${System.env.DB_ADMIN_PASSWORD}"
}

I want to run a liquibase rollbackSql and specify the tag for the rollback using Gradle property via commandline. So I execute

$ gradlew rollbackSql -PliquibaseTag=01.00 -PliquibaseRunList='schemaInit'

and get the following error message:

The Liquibase 'rollback-sql' command requires a value

It seems that the parameter -PliquibaseRunList='schemaInit' is forwarded to liquibase whereas the parameter -PliquibaseTag=01.00 is not.

Any help is appreciated.

Thanks in advance
Ulrich
